Release Version 0.23.2.0 · GafferHQ/gaffer

Apps

Added back "Remove Input" menu option for promoted plugs. This differs
from the "Unpromote" option in that it breaks the connection but keeps
the promoted plug on the outside of the box (#1678).
NodeGraph (#1679)
- Tightened rules for inserting nodes into noodles. Nodes are now only
  inserted when disabling the inserted node would create a pass-through
  equivalent to the original connection, and deleting the node will
  restore the original connection. Previously nodes could be inserted
  in such a way that one end of the connection was broken, or two new
  connections were made which had no logical in->out connection through
  the inserted node.
- Stopped highlighting connections when hovering in their middle, where
  they cannot be dragged anyway.
- Made it harder to accidentally drag a long connection by grabbing it
  in the middle - the sensitive section is now limited to a shorter
  segment near the end.

Improved output of objects and transforms which are static, but for
which motion blur has been requested via StandardAttributes. Motion
blocks are now omitted when no motion is detected (#1662).
ScriptProcedural (#1676)
- Fixed clearing of caches after procedural expansion in Arnold.
- Improved error reporting to include the node which caused the
  error.
- Added support for performance monitoring.
StandardOptions
- Added new performanceMonitor option, which enables/disables the
  performance monitoring now supported by the ScriptProcedural
  (#1676).
Duplicate
- Optimised set name computation. This knocks 35% off the time
  to compute a set in a custom downstream node with certain
  suboptimal qualities (#1682).
Fixed hangs caused by missing GIL management in SceneAlgo
bindings (#1686, #1687).

ExecutableNodes now support automatic substitution of variables in
StringPlug values, in the same way as has always been supported
by other node types (#887, #1671).
Fixed order of dispatch when postTasks exist (#1675).

Removed use of deprecated UI APIs. Specifically,
PlugValueWidget.registerCreator() has been deprecated, and all code
should use the equivalent "plugValueWidget:type" metadata instead
(#1673).

Fixed UI error when launching a ClassVectorParameter UI with
preexisting child parameters (#665, #1670).

Added Process and Monitor classes. Processes expose internal
processes such as ComputeNode::compute() and ComputeNode::hash()
to Monitors - classes which can observe the internal workings of
Gaffer via the exposed Processes (#1668).
Added PerformanceMonitor class. This uses the Monitor/Process
API to collect statistics useful in analysing and optimising
performance (#1668).
RendererAlgo
- Added outputObject() method (#1662).
- Added outputTransform() method (#1662).
ValuePlug
- Deprecated inCompute() method - use Process::current() instead
  (#1668).
FormatData
- Added workaround for unstable hash() method when compiling with
  GCC 4.4.7 (#1669).
ExecutableNode
- Moved public interface to TaskPlug. The ExecutableNode virtual
  interface is now considered to be protected, and will be made
  so in a future release.
ScenePlug
- Fixed python binding for pathToString().
- Added helpers for accessing globals and set names. These manage
  the context such that it is friendlier to the hash cache, by
  removing variables we know to change frequently but which cannot
  affect the result #(1683).
